UV STABLE, IMPACT RESISTANT, FLAME RETARDED ABS COMPOSITION Abstract of the Disclosure UV stable, impact resistant, flame retarded ABS compo- sitions are obtained by compounding ABS with nitrile rubber, surfactant, Diels-Alder adduct of 2 moles of chlorocyclopentadiene and 1 mole of cyclooctadiene (commonly known as Dech Plus) and antimony oxide. Such compositions consist essentially by weight of from about 1% to about 9% nitrile rubber, from about 0.3% to about 5% surfactant, from about 14% to about 30% Dech Plus, from about 4% to about 20% antimony oxide and from about 50% to about 80.9% ABS. The ABS constituent has an Izod Impact Strength of at least 1.5 foot- pounds per inch. The nitrile rubber is preferably acrylonitrile-butadiene copolymer containing by weight from about 15 to about 50% acrylonitrile component, and the surfactant is preferably siloxane oxyalkylene copolymer. The compositions have Izod Impact Strengths ranging from 2.0 to 4 foot-pounds per inch and in most cases a V-O (UL94) flammability classification.
